SIGNATURE-DELIVERY MECHANISM FOR PRINTING PRESSES.

Application filed March 26, 1926. Serial No. 97,634.

The object of my invention is to provide novel means for dellvermg a wide range of signatures wlth a minimum number of transfers to one or both of two delivery points.

located one over the other, by providing two signature delivery carriers and a common folding carrier and making the carriers of certain relative sizes and providing them with a certain number of sets of grippers, predetermined sets of grippers beingused to deliver predetermined signatures, the signature delivery points being at the same,

time so placed and spaced as to ensure theready removal of the signatures from the. lower delivery point.

My invention more particularly comprises upper and lower packer delivery carriers, upper and lower signature deliveries and a common folding carrier, one of the delivery carriers being the same diameter as the folding carrier and the other delivery carrier being three fourths the diameter of the folding carrier, the folding carrier being provided with four equally spaced sets of grippers, the larger delivery carrier with two equally spaced sets of grippers and the smaller delivery carrier with three equally spaced sets of grippers.

A practical embodiment of my invention is represented in the accompanying drawings which illustrate in vertical lon itudinal section that part of the signature delivery mechanism of a rotary web printing press which includes my invention.

The sheets cut from the web are collected and folded in any well known or approved collecting and folding mechanism, the folding carrier 1 which acts also as a transfer carrier, being shown as provided with four equally spaced sets of grippers 2, 3, l, 5. This folding carrier is arranged to transfer various signatures, as will be hereinafter brought out, to one or both of two rotary signature delivery carriers located one over the other.

()ne of the signature delivery carriers, in the present instance the upper carrier 6, is shown as being three fourths the diameter of the folding carrier 1 and as being provided with three equally spaced sets of grippers 7, 8, 9. The other signature delivery carrier, in the present instance the lower carrier 10, is shown as being the same diameter as the folding carrier 1 and as being provided with two equally spaced sets .of grippers 11, 12.

T pa er d i e es or he s gna ur e e y ca i a e denoted l3 audit nd e ar anged ne ove t e ethe which Pac r d ve ies m y b at ny a 1.1. kn ppr ed co st ct o Sl ters 15m 16 m y e p ovide for bu t ng the si 3 e.- ures apa a they are delivered f om this i rs nthe p ke d liv ri s.

It i t b unde t dtlia the posi ons of the smaller and larger signature delivery carriers may be reversed, altheugh the positions own are pr fer ed, as t all w suf icient room for the operation ofthe upper packer fingers, for a convenient arrangement of the packers and for a maximum space between them for gaining ready access to the signatures in the lower pacflxer delivery. I 1

It will be understood that any well known 79 or approved means, not shown herein, may be employed to drive the folding carrier and signature carriers, to operate the grippers and to operate the packer delivery fingers.

The delivery mechanism herein show-n operable .to deliver signatures of 8s, ltjs or 32s and particularly signatures of six 8 s in duplicate, six 16s and three 321s.

\Vhen delivering six 8s in duplicate, the four grippers on the folding carrier and I both sets of grippers on the lower delivery carrier 10 are used, the lower l1ivery carrier taking every other signature from the folding carrier and the remaining signatures being taken off by the upper three-Way delivery carrier.

When delivering six 16s, two of the sets of grippers on the folding carrier and one set of grippers on the lower delivery carrier are used, thus permitting every other signal ture to be taken off by the upper delivery carrier.

WVhen delivering three 328, only one set of grippers on the folding carrier is used and both sets of grippers on the lower delivery carrier 10 are silenced, the entire spaced apart sufficiently to give ample room for the operation of the upper packer fingers and the removal of the product from the lower packer delivery. M

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention; hence, I donot wish to be limited to the particular embodiment herein shown and described, but- What I claim is 1 1. A signature delivery comprising two signature delivery points, two signature delivery carriers therefor, one having two equally spaced sets of grippers and the other having three equally spaced sets ofgrippers,-and a common folding carrier having four equally spaced sets of grippers 7 said grippers being operable to deliver various signatures to one or both of sald dellvery carriers."

2. A" signature signature delivery points, two signature delivery carriers therefor, one having two 'equ'allyspaced sets of grippers and the other having three equally spaced sets of grippers, and a common folding carrier having four equally spaced sets of grippers said grippers being operable to deliver Ss or 16s to bothof said delivery carriers or 32s 7 to one :of said delivery carriers.

3. A signature delivery comprising two signature, delivery polnts, two signature delivery carrlers therefor, and a common folding car'rier, one of the delivery carriers being the same diameter'as the folding carrier and the other delivery carrier being three fourths the diameterof the folding carrier, the folding carrier qhaving four equally spaced sets'of grippers, the larger delivery carrierhaving two equally spaced sets of grippers and the smaller delivery, carrier having threeequally spaced sets of grippers,

said grippers being operable to deliver va-,

rious signatures to one or both of said delivery points.

4. A signature delivery comprising two signature delivery points, two signature delivery carriers therefor, and a common fold 5 A signature delivery comprising two signature delivery points arranged one over delivery comprising two the other, two signature delivery carriers therefor arranged one over the other, and a common folding carrier, one of the delivery carriers being the same diameter as the folding carrier and the other carrier being three fourths the diameter of the folding carrier, the folding carrier having four equally spaced sets of grippers, the larger delivery carrier having two equally spaced sets of grippers and the smaller delivery carrier having three equally spaced sets of grippers, said grippers being'operable to deliver various signatures to one or both of said delivery points. i a i r 6. A signature delivery comprising two signature delivery points arranged one over theother, two signature delivery carriers therefor arranged oneo vervtherother, and a common folding carrier, one of the deliverycarriers being the same diameter as the folding carrier and the other carrier being three fourths the diameter of the folding carrier, the folding carrier having four equally spaced sets of grippers, the larger delivery carrier having two equally spaced sets ofgrippers, said grippers being operable to deliver .8s or 16s to both of said delivery points and 32s to one of saiddelivery points.

7. A signature delivery comprising two signature delivery points arranged one over the other, two signature delivery carriers therefor arranged one over the other, and a common folding carrier, the lower delivery carrier being the same diameter as the folding cylinder andthe'upper. delivery carrier being three fourths the diameter of the folding carrier, the folding carrier having four equally spaced sets of grippers, the lower larger delivery carrier having two equally spacedsets of grippers and delivery carrier having three equally spaced sets of grippers, said grippers being operable to deliver Various signatures to one or both of said delivery points.

8. A signaturev delivery comprising'two signature delivery points arranged one ove the other,'two signature delivery carriers therefor arranged one over the other, and a common folding carrier, the lower delivery carrier beingthe same diameter as the folding cylinder and the upper delivery carrier being three fourths the diameter of the folding carrier, the folding-carrier having four equally spaced sets of grippers, the lower larger delivery carrier having two equally spaced sets of grippers and the upper smaller deliverycarrier having three equally spaced sets of grippers, said grippers being operable to deliver 8s or l6s to both of said delivery points and 32s to one of said delivery points.

In testimony, that I claim the foregoing as my invention, I have signed my name this th day of March, 1926. I
